Hi Debbie,
Yes, I had found the Edgecombe girls on Papers Past just a few days ago - a very sad story. Because of the age match with my Alice, and other info I've been given that ties in, I'm assuming this is my Alice. I didn't know my Alice had a sister, as I know nothing of her birth or parents.
Since finding that article another relative has discovered a Mabel Edgecombe, who married a Hubert Johns in Manaia, Taranaki, NZ in 1903. She found this through info on someone's tree, and it says that Mabel was b.1882 in British North America. This birthdate also ties in with the Mabel's age of 10 yrs old in 1892, in the newspaper article. No other info on the tree about her prior to her marriage.
My father has told me that Alice's daughter (who was my Dad's cousin) always said her mother was American, so, along with the Papers Past article, and Mabel who married here in NZ, we feel quite sure that the Alice we're looking for is the sister of this Mabel.
Now, it's just a matter of finding them in this British North America place, and the shipping records for their trip to NZ, sometime between 1885 and 1892. And of, course, what happened to the parents of these two girls.
Thanks so much for taking the time to look into this.
Cheers,
Suzanne.
